Phase transition occurring during cycling plays a fundamentally important role in the cycling performance of nickel-rich cathodes. Here, splitting of two O3 phases, rather than the often observed O1 phases in the conventional LiCoO2 electrode, was discovered in LiNi0.85Co0.10Mn0.05O2 at a high-voltage region (>4.6 V). Such degradation could be mitigated via Al doping.

高压循环过程中富镍层状阴极降解机理的结构解析。

循环过程中发生的相变在富镍阴极的循环性能中起着根本性的重要作用。在此，在高压区域（> 4.6 V）的LiNi0.85Co0.10Mn0.05O2中发现了两个O3相的分裂，而不是常规LiCoO2电极中经常观察到的O1相的分裂。这种劣化可以通过Al掺杂来减轻。
